Technical scheme of the present invention, provides and is a kind ofly mainly used in the operation system of Java technique construction based on non-intrusion type performance monitoring technology in the operation system of Java technique construction, can the daily record monitoring problem of resolution system when running.Technical solution of the present invention difference with the prior art is: with original operation system code, logic is isolated, i.e. the daily record monitoring implementation method of non-intrusion type.By the application of technical solution of the present invention, on the basis of not revising original system code, the concrete state of system cloud gray model (as variable, parameter etc.) daily record can be got as required, facilitate the diagnosis of problem and the monitoring of system.
For 3 problems mentioned in prior art, the target that the present invention will realize the realization of non-intruding original system needs to solve following two problems:
(1) how execution point concrete in the System implementation program that will monitor is described;
(2), how by not revising original system code, its monitoring script being performed in java runtime environment-Java Virtual Machine, and gets daily record.
In technical solution of the present invention, each module diagram is as Fig. 5.Each building block technique realizes as follows:
(1) TRACE script: for describing the position and monitoring logic that will monitor code, and call daily record API print log in monitoring script method.Concrete example is as follows:
。
Wherein:
1.@Trace---for identifying this code script is monitoring, tracing script.
2.@OnMethod-for defining the position of monitoring is method, defines concrete content in code block.In addition OnExit-method is also had when exiting, OnTimer(millisecond)-the execution time is when exceeding threshold value etc.
3. TraceExecute method is the manner of execution of monitoring logic, for print log information.
It should be noted that in the definition of script rule and need some point in application programs to carry out security control, such as, generally static variable can not be changed, can not process etc. program exception.
(2) script executing engine: for resolving script, becomes concrete rule to identification (RNC-ID) analytic wherein; Call byte code operations instrument to rewrite according to rule the code information described in script.In Java platform, corresponding Technical comparing is ripe, as ASM etc.
(3) bytecode crossover tool: as implied above, by bytecode crossover tool, directly can revise the byte code files after compiling in Java platform, replace to target byte code file.
(4) Agent agency and the Attach interface in VM: application program process number in an operating system can be got by attach API in virtual machine, and by calling Agent Agent, monitoring tools and application program virtual machine be established the link.
(5) instruction set: the virtual machine of Java platform provides the instruction set of one group of bytecode operation, and provides corresponding API, such as, replace the byte code files run in virtual machine.
In technical solution of the present invention, flowchart is as Fig. 6.The whole process performing monitoring is described in this process flow diagram.Wherein when execution byte code files is replaced, need first to preserve original byte code files.Mainly because for runtime system, when not needing during operation when program condition monitoring, can Dynamic-Recovery.
To the java applet class file of all couplings as drag in example below:
With java.io beginning, and comprise in title input character and using read beginning program technic name as control point.The method that print routine is performing.As shown in Figure 7.
Compared with prior art, the maximum advantage of technical solution of the present invention is: when not changing system code and realizing, when can be implemented in system cloud gray model, carrying out monitoring record to internal system code implementation status, there is not coupled relation in the logical and original system logic that realizes of monitoring; Relative to existing scheme, there is greater flexibility, can elevator system daily record diagnosis and monitoring capacity greatly.
Technical scheme of the present invention, adopts at present in concrete project problem diagnosis.
More than be described with reference to the accompanying drawings technical scheme of the present invention, considered in correlation technique there is no easy, the unified solution for complicated type non-intrusion type performance monitoring.Existing non-intrusion type performance monitoring cannot complete the non-intrusion type performance monitoring process that complicated type participates in.Therefore, to the present invention proposes in a kind of operation system non-intrusion type method for monitoring performance in non-intrusion type performance monitoring apparatus and a kind of operation system, can on existing non-intrusion type performance monitoring mode basis, make full use of the non-intrusion type performance monitoring that single object type completes multi-object type, set up general, the unified monitoring thinking of the non-intrusion type performance monitoring that multi-object type participates in.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
